The Australian pop-punk band 5 Seconds of Summer appeal to the young fans of One Direction, their touring buddies and fellow boy band-ers, as well as the fans of pop punks mainstays like Blink 182, All Time Low, Mayday Parade, and Green Day, which the band has cited as their major influences. The four-piece band, including Luke Hemmings, Calum Hood, Ashton Irwin, and Michael Clifford rose to fame first as YouTube stars, after posting Mike Posner and Chris Brown covers on Hemmings’ YouTube Channel. Their debut self-titled album featured original songs penned by the band, with the exception of their third single, “Amnesia,” which was written by Benji and Joel Madden of Good Charlotte, giving them some real pop-punk street cred. Their shows attract hoards of teen girl fans, so expect an upbeat, energetic show where every lyric is echoed by the screaming masses. Front man Clifford comes from the Green Day school of performance, clearly studying the Billie Joe Armstrong style but still putting his own twist on it. Their high-energy, teen targeted shows draw massive support on social media, but are even more exciting in the moment.
